Precipitated barium sulfate does not change color when it meets hydrogen sulfide

There are two types of barium sulfate, one is precipitation, the other is water washing. Barite is produced. Industrial products include barite crushing and barite precipitation by chemical reaction with barite as raw material.

Barium sulfate dissolves in acid-base metal salts and becomes barium carbonate. 

Its texture is very fine and soft. Its oil absorption and covering power are higher than barite powder. It is stable to air and heat, and does not change color with hydrogen sulfide and toxic gases.
